Martin,
Thanks for the answers. I will test them tomorrow.
As for QgsLegendInterface the problem was that I did not know how to
use it correctly!
Cheers,
Benoit

Colormap is given to the raster (and into the coloramp tab in the

info. So far so good. But, the legend does not refresh to show the
change to
colormap: the raster icon and raster colour bar stay grey.
Use QgsLegendInterface class to refresh the symbology:
iface.legendInterface().refreshLayerSymbology(layer)
The main raster (the only layer in my test) does not refresh either
in the
QGIS map canvas window. Only if I move it will it refresh and
display the
colour map.
Possibly you're using caching. Make sure to clear the cached image
before calling triggerRepaint():
layer.setCacheImage(None)
The only way to refresh the legend to the correct info seems to
open the
raster properties box and click ok. (I've tried the
QgsLegendInterface, but
I have problems to make it work!)
What probles with QgsLegendInterface did you have?
Regards
Martin
